Multiple coronary stenting in unstable angina: early and late clinical outcomes.
We examined clinical outcomes in 110 consecutive patients with unstable angina who underwent multiple coronary stenting over a 32-mo period. The main outcome measures were death, stroke, myocardial infarction, bypass surgery, and repeat angioplasty. The angiographic success rate was 100%, and the procedural success rate was 96%. There were no in-hospital deaths and five (4.5%) patients had a myocardial infarction prior to discharge. There were four (3.6%) stent thromboses with one (0.9%) patient requiring urgent bypass surgery and two (1.8%) requiring repeat angioplasty. At late follow-up (11.9+/-7.1 mo), there was (0.9%) death and three patients (2.8%) suffered myocardial infarction. Three (2.8%) patients underwent late bypass surgery and five (4.6%) had a repeat angioplasty. At follow-up, 86% of patients were event free. We conclude that multiple coronary stenting in unstable angina may be performed with a high procedural success rate and good long-term outcome.
